Quadratic equations

2.1 for Android

The description of Quadratic equations

A simple and easy to use application to determine the roots of a quadratic equation ax²+bx+c=0. Optionally, you can draw the graphic of the function y=ax²+bx+c.
If there are no real roots, you can also get the complex roots. The application will also show you the position of the complex roots in the complex diagram.

On version 2 you can find a new design and a new feature: You can now double tap over a number to change its signal.

If you find any bug or any other issue please report here or in the YouTube video before giving a negative rating. I'll be happy to help you by helping you to get a fix.
